11. all wjmw/n-jimmy concern:

Be it known that L'Giconon W. JnoQUns, e'citiz'en of the United States,residing'at Strattord, in the county of Fair-field and Stateotccnnecticut have invented certain new and useful Improvements in DrivingMeclsi'iisnn of which the following is a specification, reference beinghad-therein to the-zic companying drawings. v

This invention rel-sites to dual transmission of rota tion in a'lXlBC-hHDlCZIl organization in which it is sometimes desirable to startandstoptwo elements or mechanisms simultaneously, and at other times tostart and stop one of them Without starting the other.

A common example out such an organize tion is "an eyeleti'ng machine inwhich the eyelets are supplied to e raceway automatically by n hopper.In such :1 machine it is usually sufiicient to feedeyelets from thehopper-to the raceway when "the eyeletsetting mechanism is in operation,under some conditions. 2 when initir iily-cha-rging the raceway and whenfor one reason or another *the supply in the *ruceway becomes partly orwholly depleted, it is desirabie to operate the eyeletieeding device ormechan'isin without operating the setting mechanism. Accordingtyan-object of the invention is to provide improved means for controllingthe transmission of rotationto two 'olen'ientsor mechanisms of anorganization. for example, the ev'elet-feeding; device orIDECllt-llllSHI-ttnd thesettingg in'echzuiisin-ot uneyeleting'mnchine,so thut'both msy'be stnrted and stopped togetherwhen-desired, end one of them may be started and stopped independentlyofthe other when desired.

Features of the invention consist in a novel organization in which twodisconnectible transmission means and their respecti-ve controlling;mechanisms "are under the control of a single actuator such as a treadle, and in which an independent lock or detent is provided to preventone ot the controlling niecha'nisins tlnpOtfltiiy from being responsiveto'the control the n'ctuah ing member. The invention is hereinillustrated as embodied in en 'eyeleting 'mnc'l'iin'e of =the typereferred to, although in various aspects the'inven'tion is not limitedto application to such machines. As shown in the drawings, theorgzinizationis such-thatu'nder certrin conditions the more s'ct'oi depressing afit'readl'e rod trips'the clutch that transmits rotation 'tothe eyelet-setting mechanism and simultaneously establishescoupled"relation between a driving element end means for trn'nsmittingrotation from theletter to the eyelet feeding device, while the mere actof releasing the treadle-rod "effects disconnection of the settinginecl'urnism "and the eyelet-feeding device from their sourceorsources'o'f power. The independent lock or deten't, as a part oftheillustrated organization, 'is usahleet will to maintain the aforesaidclutch in uncoupled condition when it is desired merely to operate theeyelet-feeding device. This provides for effecting sing-leer dueltransmission by a single treadle arranged to be operated in the salnemenner for both purposes, the locking device being eflective merely 'totake control of the clutch ten' por'erily sncl to restore the clutch tothe dual control of the'treadie whenever desired.

A represents n portio'n of the machine frame having 'jou'rnele'd in theupper portion thereof th'e'inec lmnisin actuating shot't lon which lSjUUlIltIlOCl a drivcpulle'y'Q, and to which is made fast ii handwheel 3,the drive pulley 2 having an ennular flange 4 the external surface ofwhich is conical and the inner surface ofwhich is engageshie b thecilntchelements of 'a stop mot-ion. As shown, this stop motion isconstructed as follows: Reterringto Figs. 3 .nd 4, s'sleeve 5 ismade tothe shaft 1., tli'issl'eeve having u reduced portion 6 terminating in eportion 1 provided witlrcam faces on which may ride clutch blocks '8,the portion 7, together with the clutch blocks, extending within theconical flange Journaled on the reduced portion 6 is a disc 9 having apair of substantially semi-circular flanges 10 and 10 spaced apart toreceive the clutch blocks 8 between them. The sleeve 5 has an outwardlyextending flange 11 against which one face of the disc 9 may bear, andis also provided with an annular recess 12 for the reception of a coiledspring 13 which bears at one end against a pin 14 fixed in the disc 9and at its other end against a similar pin (not shown) in the sleeve 5,this spring tending to turn the disc 9 to such angular positionrelatively to the cam portions 7 as to cause the blocks 8 to clutch theinside of the flange 4. To disconnect the clutch the disc 9 is providedwith a stop shoulder 15, and the flange 11 has a similar stop shoulder16. When the parts 9 and 11 are in the angular relation shown a lockingpin 17 slidable in a perforation in the portion 11 may be projected intoa mating perforation 18 in the disc 9 to lock the clutch inits-uncoupled condition. A sleeve 19 through which the pin 17 passes isformed on its outer end with depressions to receive a handle 20 fast tothe pin 17, one of these depressions, for example, that indicated at 21,being of sufficient depth to allow pin 17 to enter the perforation 18,while another such depression but of less depth will serve to retain thepin 17 entirely within the portion 11. A leaf spring 22 fixed to theportion 11 and bearing on the outer end of the pin 17 holds the pin 17projected toward the member 9 as far as the handle 20 riding in thedepressions of the sleeve 19 will permit.

Slidably mounted in aboss B of the frame A is a guide rod 25.Surrounding the rod 25, and seated on the base of the machine is aspring 'or cushion 26 having a cap plate 27 bearing on the upper surfacethereof. Seated on the plate 27 is a yoke 28 through which the rod alsopasses, and bearing against the top of yoke 28 and the urn derside ofthe bracket B is a coil compression spring 29, spring 29 and cushion 26cushioning the movement of yoke 28 in both direct-ions. Pivoted to theopposite ends of the yoke 28 are stop arms 30 and 31, these armsprojecting upwardly in the planes of rotation of the stop shoulders 16and 15 respectively. Above the boss B a pin 32 is fixed to the frame A,and on its outer end is pivoted a rock lever 33. A torsion spring 34surrounding the pin 32 normally presses the rear or left end 35 of thelever 33 upwardly (Fig. 2). A pin 36 carried by lever 33 engages a slot37 in the stop arm 31, the lower portion of this slot being an arc andconcentric to the axis of the pin 32, while the upper portion of thisslot is inclined to have the effect of a cam. By this means a downwardmovement of the end 35 initially imparts no motion to the arm 31 butfinally swings the arm out sf ("i with the stop shoulder 15. The arm 36has a cam portion 38 cut on its rear face for engagement with a roll 39carried by the arm 33, and a rod 40 pivoted thereto by means of thesupporting pin of roll 39 projects downwardly and may be actuated up anddown by the operator by any suitable means such as a treadle (notshown).

Journaled in a bracket C near the top of the machine is a drive shaft 41connected by gears 42 and 43 to drive the feeding ele ment of a hopperwhich in this instance is designed to supply eyelets. Raceways 45 areprovided for conducting the eyelets downwardly to the setting mechanism.Shaft 41 is held against endwise motion by collars 46 and 47 fastthereto, and near its outer end it carries a pin 48 riding in a slot 49in the hub 50 of a conical friction wheel 51, arranged to engage anddisengage the conical outer surface of the hub 4. A collar 52 is madefast to the inner end of the hub 50, and a spring 53 surrounding theshaft 41 and bearing against the collars 47 and 52 normally urges thefriction wheel 51 into driving engagement with the hub 4. Fixed to theupper portion of bracket C is a bar 54 carrying at its outer end a pairof rolls 55 which engage twin cam portions 57 of a rod 56. This rod actsagainst the collar 52 to prevent the spring 53 from pressing the wheel51 against the flange 4 of the pulley, and is forked as shown in Fig. 2,to straddle the hub 50 and bar 54. The lower end of rod 56 is pivoted at58 to an arm 59 made fast to the lever 33.

The operation of this mechanism is as I follows:

When the clutch and transmission train are uncoupled the parts occupythe position shown in the drawings, the rear end of the lever 33 beingin its upper position, the roll 39 engaging the stop arm 30 and holdingits upper end beneath the stop shoulder 16, while the pin 36 within theslot 37 holds the stop arm 31 in engagement with the stop shoulder 15.As above described, in this position the clutch blocks are out ofcontact with the inner surface of the flange 4, hence the shaft 1 is inunclutched condition. At the same time the rod 56 is in its depressedposition, where it maintains the friction wheel 51 out of contact withthe hub 4. The pulley 2 may therefore rotate without driving any of themechanism.

When it is desired to drive the machine the operator depresses the rod40 whereupon the pin 36 riding within the slot 37 moves the stop arm 31out from beneath the shoulder 15 to permit the spring 13 to apply theclutch for the shaft 1. As the lever 33 is rocked to start the shaft 1,the rod 56 is pushed upwardly allowing the spring 53 to force thefriction wheel 51 into driving engagementwith the flange 4. In thisposition of the parts both the mechanism actuating shaft 1 and thearticle feeding mechanism 44 are coupled to the pulley 2..

When it is desired to stop the machine. rod 40 is allowed to rise underthe action of the torsion spring 34;, this actioin scrv'ng to depressthe rod 5 6 and retract the friction wheel :31 from theflange is. Italso brings the stop arm 31 into the path of motion. of the stopshoulder 15, which is theucupon caught and held from notation. Themomentum of the shaft 1 and. parts actuated thereby continues therotation of the sleeve 5,. thus releasing the clutch, compressing thespring 13 and carrying the shoulder 16 past the end of the stop arm 30.The last portion of the motion of the lever 33, wherein the pin 36 ridesin the concontric portion of the slot 37, imparts nomotion to the arm31, but serves to force the arm 30 against the flange 11 beneath the lug1-6. 'When the momentum of the machine has been spent, the. spring 13reacts to impart a reverse rotation to flange 11, whereupcn the shoulder16 is brought into contact with the arm 30b which it is arrest-ed toretain the clutch blocks 8 in unclutched position with. relation to theflange 4;. During the stopping; the spring and cushion members 29 and2.6 serve to cushion the thrusts imparted to the arms 30 and 31.

Yhcn it is t'lcsired. to actuate the article feed mechanism alone, asfor example when the raceways for any reason becomeempty, this may bedone without starting the machine, which if started would take sucharticles from the :accways and waste them. The operator moves the handle20 to the depression 21 whereupon. the spring 22 forces the locking pin17 into engagement with the flanges, thus locking: the clutchingelements in uuclutchcd relation as shown by Fig. 3. If the operator nowdepresses the rod ll) it will rock the lever 33 and displace the arm 7 1f om the stop shoulder 13 as before, but the spring 13 is now preventedby the pin lT from applying the clutch 1 so this action of arm 31 ismerely an idle motion. It should be noted that at this time the shaft isfree to be turned by means of the hand wllccl Ii. The rcd 56, however,is raised as before. allowing the spring 53 to move the friction wheel51 into driving engagement with the hub l. whereupon the transmissionmeans for the t red mechanism is set in operation, ()n 2illt)\\'l!i}il1t rod ill to rise again, rod 56 is depressed and the friction wheel.31 is removed from driving engagement with the flange l. and the arm 31is again moved in under the stop shoulder 15 the parts bcin; then instopped position. By turning the handle 20 to retract the locking pin 17the clutch for the shaft 1 will be re stored to the control of the rod40.
